NAME

       ALTER VIEW - change the definition of a view

SYNOPSIS

       ALTER VIEW name ALTER [ COLUMN ] column SET DEFAULT expression
       ALTER VIEW name ALTER [ COLUMN ] column DROP DEFAULT
       ALTER VIEW name OWNER TO new_owner
       ALTER VIEW name RENAME TO new_name
       ALTER VIEW name SET SCHEMA new_schema

DESCRIPTION

       ALTER VIEW changes various auxiliary properties of a view. (If you want to modify the view's defining query, use CREATE OR REPLACE VIEW.)

       You  must  own the view to use ALTER VIEW.  To change a view's schema, you must also have CREATE privilege on the new schema.  To alter the
       owner, you must also be a direct or indirect member of the new owning role, and that role must have CREATE privilege on the view's  schema.
       (These  restrictions  enforce  that altering the owner doesn't do anything you couldn't do by dropping and recreating the view.	However, a
       superuser can alter ownership of any view anyway.)

PARAMETERS

       name   The name (optionally schema-qualified) of an existing view.

       SET/DROP DEFAULT
	      These forms set or remove the default value for a column.  A default value associated with a view column	is  inserted  into  INSERT
	      statements on the view before the view's ON INSERT rule is applied, if the INSERT does not specify a value for the column.

       new_owner
	      The user name of the new owner of the view.

       new_name
	      The new name for the view.

       new_schema
	      The new schema for the view.

NOTES

       For historical reasons, ALTER TABLE can be used with views too; but the only variants of ALTER TABLE that are allowed with views are equiv-
       alent to the ones shown above.

EXAMPLES

       To rename the view foo to bar:

       ALTER VIEW foo RENAME TO bar;

COMPATIBILITY

       ALTER VIEW is a PostgreSQL extension of the SQL standard.
